At an amusement park there are 200 kg bumper cars A, B, and C that have riders with masses of 40kg, 60 kg, and 35 kg, respectively. Car A is moving to the right with a velocity Va=2m/s when it hits stationary car B. The coefficient of restitution between each car is 0.8. Determine the velocity of car C so that after car B collides with car C the velocity of car B is zero.
